Application filed December 18, 1913. Sera1No. 807,504.

To all w71 om it may concern s Be it known that l, MARY E. WELCH, a

citizen of the United States, residing at Pontiac, county of Oakland, State of Michigan, am administratrix of the estate of ALLIE R. iVELcI-I, deceased, late of Pontiac,

ings, which form a part of this specication.

This invention relates to horns in which the sound is produced by vibrating a diaphragrn.

The horn is mounted just behind the radiator and within the hood. The actuator of the diaphragm is mounted upon the fan I lshaft and driven from powertaken from the fan pulley.

The advantages of the location and the novelty of the construction will more fully appear in the detailed description follow-- ing. I

Figure l, is a rear elevation of the horn, the actuator, the fan and the support for same, the horn being partially sectioned. Fig. 2, is a plan `view of the saine parts. Fig. 3, is a section on the line A-A of Fig. 1. Fig. 4, is a phantom view of the radiator showing the horn and fan in full lines.

An arm a supports the fan shaft b that is screwed into it. Upon the forward end of the-fan Shaft is rotatably mounted the fan c that is provided with a hub d which enlarges to form the pulley e. The fan is held on the shaft by the head f of the fan shaft. The arm 'a has an integral laterallyprojecting sleeve f/ that fits over the fan shaft b. The exterior of this forms a bearing for the actuator h, the latter of which is in the form of a toothed wheel that in rotation engages against the point z' on the diaphragm j. This diaphragm is mounted at the closed end of the horn c. The horn is of elbow form, opening4 with a dare just behind the radiator so as to send the sound through the interstices of the radiator.

Between the actuator' L and the pulley e a fiber or friction wheel Z is mounted upon the sleeve a. A spring lever m is normally tending to pack the actuator la, and the friction wheel l against the pulley so that the pulley will rotate the actuator. This packing tendency, however, is resisted and normally overcome by the coil spring n that holds the power end of the lever. power end of the lever is also provided with lafshifting arm o which engages the side of the actuator that lies toward the friction wheel. of contact with the friction wheel and pulley" so as to insure the cessation of rotation and also acts as a brake to stop rotation.

The post 79 is bolted to an extension q of the arm c. This post 72 supports the spring n, and also a tubular sheathing r for the rod s that is attached to the end of the lever and which runs to a place where it may be reached by the driver. By pushing this rod, the pull of the spring n, is overcome and the spring end .of the lever m is allowed to bear against the actuator so as to bring it into operative relation with the pulley Z. This sounds the horn. lVhen cessation is desired all that is necessary is to cease pushing upon the rod s and the spring n then draws the lever out of engagement and the shifting arm 0 insures separation-of the actuator and the friction wheel.

The pin t protrudes through a hole in the spring lever and acts as a guide. The ring- The This serves to pull the actuator out like end of the spring lever that fits over the sleeve g binds or cramps upon the sleeve when the spring n is holding the lever back. This binding and cramping action prevents the spring packing the actuator, the friction wheel and the pulley, until the power end of the spring lever is released.

, lVhat I claim is:

1. The combination of a rotating element, a shaftupon which the rotating-element is mounted to rotate, a diaphragm held adjacent to the shaft, an actuator mounted to rotate upon the shaft, a friction wheel between the actuator and the rotating element and a spring by which the actuator, friction wheel and rotating element may be packed when desired.

2. The combination of a rotating element, a shaft upon which the rotating element ,is mounted to rotate. a diaphragm. supported adjacent the shaft, an actuator supported to rotate about the shaft, a friction wheel between the actuator and the rotating clement, a spring lever tending to pack the actuator, friction wheel, and rotating element, and a spring normally holding the spring lever out of engagement with the actuator, substantially as described.

The combination of a rotating element, a shaft upon which the rotating element is mounted to rotate, a friction Wheel ,mounted around said shaft adjacent Said rotating element, a diaphragm held adjacent the shaft, an actuatoi1 mounted to rotate around said shaft adjacent the friction wheel, a spring lever having a ring-like 'terminal tending to engage said actuator, a spring for holding' the spring lever out of engagement with the actuator so as to prevent the packing of thc actuator, friction Wheel and rotating element, and a shifting arm attached to tire lever for insuring the separation of the actuator, friction wheel and rotating element, substantially as described.

4l. The combination with a rotating element, of a shaft upon Which the rotating element is mounted to rotate, a sleeve mounted on one cnd of the shaft, a friction Wheel mounted to rotate on the sleeve and lying adjacent the rotating element, a diaphragmiheldadjacent the sha-ft, an actuator rotatably mounted upon the sleeve adjacent the friction wheel, a spring lever havinga ring-like portion around the sleeve tending to engage said actuator and adapted to cramp upon the sleeve When the end of the lever is pulled and means for normally holding the lever in a constrained position so as to cramp the ring at its end 'upon the sleeve,

whereby when the end of the lever is released the spring lever packs the actuator, friction wheel, and rotating member, sub stantially as described.

In testimony whereof, I sign this specification in the presence of two Witnesses.
